Mount & Blade II: Bannerlord

Mount & Blade II: Bannerlord

Harmony
Everytime I download Harmony or ANY mod it seems, Bannerlord won't even launch. Why?
I don't even get an error message, The mouse spins for a second and the game doesn't start. Requires a fresh install everytime to run vanilla as the files seem to corrupt. Absolutely enraging. I played on xbox for years and I was excited to use mods.
